<span>Given that RS = 6, ST = 3, and SL = 4, to find NS, we first find QS.

Notice that NQS forms a right triangle with the right andle at Q.

To find QS, we notice that QRS forms a right triangle with the right angle at R.

Note that ST = QR = 3 and RS = 6.

Using pythagoras theorem
QS^2=QR^2+RS^2=3^2+6^2=9+36=45 \\  \\ QS=\sqrt{45}

Note that NQ = SL = 4.

Using pythagoras theorem
NS^2=NQ^2+QS^2=4^2 + 45=61 \\  \\ NS= \sqrt{61}</span>

Svetradugi [14.3K]

Answer:

173 days

Step-by-step explanation:

The formula for substantial presence test is;

SBT = (Total of number of days present in the current tax year) + (1/3)(number of days in the year that was before the tax year) + (1/6)(number of days in the year that was two years before the tax year)

From the question, present tax year is 2019 and number of days is 96 days.

Year before tax year is 2018 and number of days is 198 days

2 years before tax year is 2017 and number of days is 66 days.

Thus;

SBT = 96 + ((1/3)198) + ((1/6)66)

SBT = 173 days

Data are collected on the 35 students in a college history course. Which of the following is not a variable for the data set?
Nesterboy [21]

Answer:

(E) Number of students in the data set

Explanation:

A variable, in research and data collection, refers to something that is being measured and can have changing values.  

The example above shows that student birth month is a variable since we can have a range of options from January to December. Political affiliation is also a variable since the students can state whether they follow certain political parties or even whether they do not. Student age is a variable too, with answers from a range of numbers such as 20-25, since they are college students. Student address is a variable as well since students will have varying answers, be it those who live in the same address or different ones.  

However, number of students in the data set is not a variable – it is instead the number of research participants. It can be a population or a sample, depending on what the research is about.

What is the slope between the points (8, -2) and (-7, 10)​
sdas [7]

Answer:

-4/5

Step-by-step explanation:

use point slope form, which is y2-y1/x2-x1

plug in the numbers to get 10 -(-2)/-7-8. double negatives make a positive, so -2 turns into a positive. so adding them together makes 12/-15. simplify it to get -4/5.
